Labo Élec

Standard electrical symbols (IEC 60617)

The circuit diagram symbols used in the course and in the simulator's schematic view: source, cell, resistor, lamp, switch, capacitor, coil, measuring instruments. IEC 60617 standard, in use across Europe.

A circuit diagram represents a circuit with symbols joined by lines: each line is an ideal conductor, each symbol a component. The IEC 60617 standard fixes the drawing of each symbol so that a diagram reads the same way everywhere. In Labo Élec, the schematic view draws itself from the circuit built on the breadboard.

Reading a diagram

  • The generator (source, cell) sets the voltage; current leaves its + terminal and returns to the − terminal.
  • An open switch breaks the loop: no current flows in that branch.
  • The voltmeter connects in parallel (across the terminals), the ammeter in series (in the branch).
  • A resistor is drawn as a rectangle (IEC); the zigzag is the American notation (ANSI).

Circuit diagram CEI 60617

How does it work?

The perfboard: each big hole is a circuit node. You push a single leg of a component (resistor, lamp...) into it. The 4 small holes around it are connected to it: that is where chips and leads plug in.

  1. Drag a component onto the board: it snaps onto the grid. R rotates it.
  2. To join neighbouring big holes, click Jumper chip in the palette (or C) then drag on the board: a line of chips is laid at once. Bridged holes become a single node.
  3. For long links and for the power supply (placed next to the board), drag a lead from one big hole to another (or to a terminal).
  4. As soon as a loop is closed, the circuit is solved in real time (Ohm + Kirchhoff) and the diagram follows.
  5. Zoom with the wheel (or + / −, two-finger pinch); drag the background to pan, 0 fits the board. The + buttons around the board add a row or a column.
